Exim Configuration Editor

[vikins]

AFAICT, you cannot disable these in the Exim Configuration Editor. You can, however, do it by editing /etc/exim.conf and /etc/exim_outgoing.conf (if you have that one) and changing the line:

headers_add = "${perl{mailtrapheaders}}"

to this:

# headers_add = "${perl{mailtrapheaders}}"

Then stop and start Exim. If your exim.conf is ever recreated, you'll have to redo the mod.

I've been using this method of editing /etc/exim.conf for a long time. We now how the Advanced Exim Configuration editor available in WHM. I see this section in there, but it does not seem to be editable. Can anybody comment if there is a way to make the above change through the editor so that it will be preserved during exim updates and rebuilds?

Thank you.

Hello,

The following post from another analyst might help:

The X-AntiAbuse headers are added by the following in the routers in exim:

headers_add = "${perl{mailtrapheaders}}"

I was able to remove these headers in testing,  but this required basically a complete re-write of Section: POSTMAILCOUNT in Exim's advanced editor as the editor does not let you easily edit these default routers.

Basically,  I copied the whole section,  renamed the routers,  commented out the headers_add lines here and pasted the whole lot into the POSTMAILCOUNT input window in Exim advanced editor.

What is the "supported" cpanel way of removing these headers ?

 

[cPanelMichael]

There's no supported method, however there is a workaround referenced in my previous response.

Thank you.

 

[brsnik]

When the server gets restarted, settings are overwritten. Headers are shown again...

What is a way to change it without it getting overwritten??

 

[cPanelMichael]

When the server gets restarted, settings are overwritten. Headers are shown again...

Could you let us know the specific steps you took, and what in-particular was overwritten?

Thank you.

Hello,

The correct way to do this, is I guess, editing the perl script that generate headers. (don't forget to make a backup of this file before editing)

nano /etc/exim.pl.local

Then, you carefully should be able to search (ctrl+w) and modify all variables containing : "X-AntiAbuse"

After restarting that config may not be overwritten.
